[ UV Coatings for Mobile Phones ]

Mobile phone UV coating, part of the first on the substrate of the thermoplastic acrylic paint, after the UV cover light, part of the UV varnish directly on the substrate. There are two systems and three systems for the construction of mobile phone plastic casing. The two systems are mainly based on the primer thermoplastic acrylic paint + UV topcoat. The three systems are two-layer color palette + UV topcoat. Painting. High-temperature baking type coatings are used for the coating primer and topcoat of the magnesium-aluminum alloy part.

The UV performance requirements of mobile phones are different due to different quality requirements. The basic requirements are: adhesion, leveling hardness, gloss, high and low temperature cycle test, crack resistance, high temperature and high humidity resistance, wear resistance (RCA), Chemical resistance, salt spray resistance, etc. The main performance requirements are adhesion, hardness and high and low temperature resistance and wear resistance. At present, for some high-end mobile phone varieties, the requirements of hand sweat resistance, water resistance and vibration wear resistance are put forward.
